Field Summary

static String	ATTRIBUTE_COND An expression that must evaluate to true after conversion to boolean in order for the form item to be visited.
static String	ATTRIBUTE_EXPR The initial value of the form item variable; default is ECMAScript undefined.
static String	ATTRIBUTE_MODAL If this is false (the default) all active grammars are turned on while collecting this field.
static String	ATTRIBUTE_NAME The form item variable in the dialog scope that will hold the result.
protected static ArrayList<String>	ATTRIBUTE_NAMES Supported attribute names for this node.
static String	ATTRIBUTE_SLOT The name of the grammar slot used to populate the variable (if it is absent, it defaults to the variable name).

Field Detail

TAG_NAME

public static final String TAG_NAME

Name of the field tag.

See Also:

Constant Field Values

ATTRIBUTE_NAME

public static final String ATTRIBUTE_NAME

The form item variable in the dialog scope that will hold the result.

See Also:

Constant Field Values

ATTRIBUTE_EXPR

public static final String ATTRIBUTE_EXPR

The initial value of the form item variable; default is ECMAScript undefined. If initialized to a value, then the form item will not be visited unless the form item variable is cleared.

See Also:

Constant Field Values

ATTRIBUTE_COND

public static final String ATTRIBUTE_COND

An expression that must evaluate to true after conversion to boolean in order for the form item to be visited. The form item can also be visited if the attribute is not specified.

See Also:

Constant Field Values

ATTRIBUTE_TYPE

public static final String ATTRIBUTE_TYPE

The type of field, i.e., the name of a builtin grammar type. Platform support for builtin grammar types is optional. If the specified builtin type is not supported by the platform, an error.unsupported.builtin event is thrown.

See Also:

Constant Field Values

ATTRIBUTE_SLOT

public static final String ATTRIBUTE_SLOT

The name of the grammar slot used to populate the variable (if it is absent, it defaults to the variable name). This attribute is useful in the case where the grammar format being used has a mechanism for returning sets of slot/value pairs and the slot names differ from the form item variable names.

See Also:

Constant Field Values

ATTRIBUTE_MODAL

public static final String ATTRIBUTE_MODAL

If this is false (the default) all active grammars are turned on while collecting this field. If this is true, then only the field's grammars are enabled: all others are temporarily disabled.

See Also:

Constant Field Values

ATTRIBUTE_NAMES

protected static final ArrayList<String> ATTRIBUTE_NAMES

Supported attribute names for this node.
